An image forming apparatus includes a printer engine, a sensor and a processor. The printer engine forms an image. The sensor outputs vibration information associated with a vibration of the printer engine. The processor determines whether at least one component of the printer engine has an abnormality based on the output vibration information.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The image forming apparatus of claim 1, wherein the processor is to determine which of the first component and the second component has the abnormality based on at least one selected from the group consisting of: frequency analysis information of the output vibration information, and level analysis information according to time of the output vibration information.
4. The image forming apparatus of claim 1, wherein the output vibration information indicates that both the first component and the second component potentially has the abnormality, and wherein the processor is to distinguish which of the first component and the second component has the abnormality using the multiple first component frequency reference values and the multiple second component frequency reference values.
5. The image forming apparatus of claim 4, wherein a first of the multiple first component frequency reference values and a first of the multiple second component frequency reference values are at a same frequency, and a second of the multiple first component frequency reference values and a second of the multiple second component frequency reference values are at different frequencies.
6. The image forming apparatus of claim 5, wherein the second of the multiple first component frequency reference values and the second of the multiple second component frequency reference values being at different frequencies enables the processor to distinguish which of the first component and the second component has the abnormality based on the output vibration information.
12. The image forming apparatus of claim 1, wherein the output vibration information is output by the sensor in a warm-up mode or a calibration mode.
13. The image forming apparatus of claim 1, wherein the plurality of frequency reference values comprise values of vibration at respective frequencies.
16. The method of claim 15, wherein a first of the multiple first component frequency reference values and a first of the multiple second component frequency reference values are at a same frequency, and a second of the multiple first component frequency reference values and a second of the multiple second component frequency reference values are at different frequencies.
17. The method of claim 16, wherein the second of the multiple first component frequency reference values and the second of the multiple second component frequency reference values being at different frequencies enables the system to distinguish which of the first component and the second component has the abnormality based on the vibration information.
